PhysicsCircular motionSimple harmonic motionA2/A-levelOCR Created by: AntoniadfCreated on: 22-04-18 15:14 Angular Velocity The rate if change of angle for an object moving in a circular path. 1 of 12 Centripetal Force A force that keeps a body moving with a constant speed in a circular path. 2 of 12 Centripetal Acceleration The acceleration of any object in a circular path at constant speed, acts towards centre of circle. 3 of 12 Simple Harmonic Motion Oscillating motion where acceleration is directly proportional to its displacement (in opposite direction) directed towards a fixed equilibrium point. 4 of 12 Displacement The distance moved from the equilibrium position. 5 of 12 Amplitude The maximum displacement from the equilibrium position. 6 of 12 Phase Difference The difference in displacement bewteen 2 oscillating objects or at different times. 7 of 12 Isochronous Oscillator An oscillator that has the same period regardless of amplitude. 8 of 12 Damping An oscillation is damped when an external force that acts on oscillator has an effect of reducing amplitude. 9 of 12 Natural Frequency The frequency of free oscillation 10 of 12 Driving Frequency The frequency with which the periodic driver force is applied to a system in forced oscillation. 11 of 12 Resonance The increase in amplitude of a forced oscillation when the driving frequency matches the natural frequency. 12 of 12
